Thanks for posting your question at healthcare magic.
Your details are showing that you are having severe narrowing of left neural foramaina at C6-7 level.This may be most probably leading to symptoms of spinal canal
stenosis(like pain on active movement of left upper limb,radiation
of pain or abnormal sensation or heaviness at shoulder area).Your symptoms can be temporarily treated by analgesic
medicines but sure shot to get relief is surgery.
Hope this will help you.
